angle of only about 30. The continued rotation of the shaft past-an angle .of

` -causes the cylinder to reverse its direction of oscillation, and to oscillate in a clockwise direction, as shown by the arrow in Fig. 4, until an angle of about 165? is reached, the valve and its port 16, which is considerably longer than the cylinder-port 15, remaining practically stationary during thisperiod. The direction of oscillation ofthe intake valve 17 then begins to reverse, causing this valve to close and the intake passage be-V tween the cylinder and casing to be quickly closed, since the cylinder-head and valve are again ruiming in opposite directions, the closure taking place after the main shaft has rotated through an angle of about 200 de- `While the intake passage is open, fuel is supplied to cylinder 2; and upon the closing of valve 17, and return stroke of the' piston, Fig. 5, the gases in the cylinder are compressed. The cylinder continues to oscillate in a clockwise direction until an angle.

of about 27 0O is reached, after which its direction of oscillation is reversed to contraclockwise, the direction of oscillation of exhaust valve 23 also changing. The direction ot oscillation at the completion of the, second stroke is shown by the arrows in Fig. 6; all lvalves remaining closed.

The intake valve 17, exhaust valve 23, and the cylinder-head, all oscillate about the same axis, but not always in the, same direction, nor with the same velocity. These valves 17 and 23 are, as will appear from Figs. 11 and 12, portions of cylinders having the same axis as and embracing the transverse cylinder-head 2 see Figs. 9 and 10). The valves have on their outer pe,- ripheries lugs 32, 32", in which are pivoted links 31, 31", journaled at theiry lower ends on cranks 30a, 30", respectively carried by shafts 33a, 33h. These shafts arerotated by' stroke, Fig. 6, the fuel mixture is exploded by a spark from the spark-.plug 26, Fig. 2, the explosiondriving Vthe piston forward, the cylinder oscillating as shown by the arrows, and the valves remaining closed.

On reaching the position shown in Fig. 7, after `a rotationof 160 on the third stroke, the energy of the exploded gases will have been expended andthe exhaust valve 23will begin to open, the cylinder and valve now moving in opposite directions, and will be fully opened when an angle of 200.o is reached. From this point, the gases will be completely exhausted by the return stroke of the piston; the direction of oscillation'of the cylinder-head and exhaust valve changing at the position shown in Fig. 8; the direction of movement of `the intake valve .be-

ing shown 'by the arrow. The exhaust valve commences .to close when an angle of rotation of 335 is reached, at which time the of the cylinder, and ,serve as a. journal in ,which the cylinder may oscillate, as above jdescribed. The valves are supported upon and journaled Within the upper casing 20,

the latter having

openings

18 and 24 connecting with intake and exhaust pipes 119 and 25, respectively.; In the intake valve' is an opening or port 16 connecting the intake openingl in the cylinder with intake opening 18 in the casing. Similarly, in the exhaust valve an opening or port- 22 connects i exhaust opening 21 in the cylinderwith exf haust openi'ng 24- in the casing.

structed for a long period. In the particular instance shown, this period extends 'through 135 forthe admission and 140o for the exhaust. o

Instead of the valves resting on the surface of the bore of the casing, as shown, the y casing may be recessed enough to incase the valvs, so that the inner surfaces/of the valv s and casing are flush, both surfaces serving the Journal for the cylinder; or

the valves may be made tubular, a part there-- ot' completely encircling the extremities of the cylinder-head, and be placed side by that the engine is running,

an angle of 335 .masses side, having their respective openings in their relative positions; or the valves may be superimposed,one valve oscillating within the othery and the cylinder-head within the innervalve; the openings being properly located. All of the above modifications or motions are considered to be within the scope of this invention and claims.

The cylinderv is .provided with a waterjacliet il, as shown; the outer wall 10 thereof serving as the working surface of the` transverse cylinder-head, in the journal.` Circulation of Water is provided for by suitable sliding openings, or by flexible tubes connected to the oscillating cylinder,V at l2 and 13.

Fig. i3 shows diagrammatically the positions of, and extent of, o )enings in the valves during the several stro es. Assuming then, in the position shown in Fig. l, the exhaust valve is almost closed, and the piston is about to begin a down-stroke; a rotation or 5 of arc past the vertical closes the exhaust valve; all openings are entirely closed for the next two degrees; connection is then made with full opening being obtained after the shaft' has rotated through 3Go.' The intake-passa e remains fully open and admits fuel to te cylinder' until an angle of about i` is reached, after which the intake valve closes, and is entirely closed The piston now enters upon its second stroke, the compressionstroke, during which the mixed air and fuel are compressed until the-liring stage is reached, which occurs durin an interval at the end of the second stro ie and beginning of the third stroke. The gases are exploded during the tiring stage, and the piston travels on its third stroke (second revolution) until an angle of when the exhaust valve begins to open, and is fully open at 200", remaining open until is reached, when it begins to close: during stroke. the exploded gases are removed from the cylinder, the latter is cleaned to receive :fresh fuel. and the exhaust Valve closes, as shown in Fig. 1. l

The angles of opening and closing of the valves, and theI interval during which they `inay remain open and closed7 may be varied i im diiferent types of engines to meet dili'eri spirit of my ent conditions,V Without departing from the invention.

:instead of using separate admission and exhaust Valves, a single Valve, to which is imparted the propennariations in direction and speed of oscillation` maybe provided, and 'the use of asingle oscillating valve in combination with an oscillating cylinder, is

within the scopeof my invention.

While I have chosen to illustratemy ini vention, as applied to a four-cycle engine, I

160 is reached this return-stroke, the fourth desire it to be understood that it is equally applicable to engines of the two-cycle type, in which casca single valve only is used, the period of oscillation of the valve and cylinder then corresponding with each revolution of the crank-shaft.

In Fig. l5 is shown a modified form of cylinder-head. rllh'e cylinder, instead of being closed at the top, as in Fig. 2, is provided with an opening a., and the spark-plug 26 is "located at the top of the casing. By this arrangement the -pressure of the explosion will be exerted against the casing, instead of against the inside of the cylinder-head. The pressure being taken of? the cylinder, the valves will move more readily.
